Question

two number are such that the ratio between them is 3:5.if each is increased by10 ,the ratio between the new number so formed is 5:7 .Find the original number

Answer 1

Let the Numbers be 3x and 5x

We are given,

3x+10/5x+10 = 5/7

So, 21x + 70 = 25x + 50

     4x = 20

       x = 5

hence, Numbers are 3(5) and 5(5) = 15 and 25

Answer 2

Answer:

Step-by-step explanation:

Let original no. Be 3x and 5x

Acc. To condition,

3x+10/5x+10 = 5/7

21x+70=25x+50

-4x= -20

X= 5

So, the original numbers are

3x = 3×5= 15

5x = 5×5= 25
